Forward Top Skin

Time: 6 Hours

I started today with the intention of building the Vertical Power VP-X power connectors to clean up the area behind the instrument panel. What I found was the crimper that I bought from Aircraft Spruce, even though they recommend it just for this task,  was the wrong one according to Chad from VP.  

 These power connectors are very specific and need a specialized crimper. I emailed Cahd and he let me know that they have several that they loan out for free minus shipping as they are expensive, $380, to buy. He said he would ship one out at the end of the week. So I decided to stop the wiring and move on to actual building which I haven’t done for a while. The next task in the plans is to work on the forward upper skin and its parts. After cleoko’ing the skin in place I worked on the two support ribs that attach the aft sides of the skin to the windscreen roll bar. These ribs needed to be match drilled to the skins holes while making sure that edge distances are maintained. I took my time to make sure I didn’t damage the roll bar as I drilled.  

    
 One other thing I did to this area was to draw a line vertically matching the side skin below it. I have read in several blogs that guys have been cutting this piece of the skin off so the line from the side skin travels up evenly. This also allows for the canopy skirt to sit better from what I have read. So I decided to do the same and cut these tabs off. You can see the area or line in the middle photo above. Once I had all the holes match drilled I removed the skin and other parts to be deburred and dimpled.  

 Before I dimpled the skin I rolled the lower edge of the left and right side to help the skin lay on top of the side skins.  

 After the skin was done I moved to the instrument panel support structure and dimpled its flange along with the forward baggage aft walls flange. With those done I was able to rivet the instrument panel structure to the side skins as well as the top eight rivets that were left open to get the structure in place.  

    

 While I had the river gun and bucking bar out I finished the row of rivets on the right side forward skin where I had left open so I could work on the support angle on the inside for my new battery cover.  
 Not a lot of photos but a lot of work today, mainly deburring and edge work.
